Is possible to use PCI 6250 card for order power spectrum in sound and vibration

[Suraaa]

Hai all,

Iam new to Labview sound and vibration. In my application i need to extract the order power spectrum, for that iam using PCI 6250 NIcard. I tried with our NI example program i cant able to get the prober result. Whether this card is suitable for my apllication ?. If it is suitable can any one explain to me to get the order power spectrum...

In my application iam using one analog signal and one encoder signal(Speed) . Can any one Help...

Thanks in advance,

Vijay

Hi shanmugavel,

  Could you explain the scenario of your application?How are you acquiring the data?Which sensors are you using?

Thanks and regards,

iam using one accelerometer to get the signal from transaxle gear box. This accelerometer signal iam passing to charge amplifier card to get 0-10v signal. This signal iam passing to PCI6250 ai- 0 channel and encoder is connected with motor is passing to ai-1channel for analog tacho. iam using NI example program (Order power spectrum - analog tacho. VI).

sampling rate is 1000 S/s and no. of samples 1000 for acquiring data. But i cant able to get speed and order magnitude value proberly. Encoder PPR -1000. Can u help me....

Regards,

Vijay.

Hi shanmugavel,

  Instead of directly open the example( Order power spectrum - analog tacho. VI),you try to use the basic analog input acquisition program(you can find this  also in examples) and see the waveform..

Thanks for your reply

Basic Analog input is OK i can able to get analog input in Order spectrum also, my problem is not able to get prober Order magnitude and analog Tacho speed.Iam connected encoder to analog input signal channel 1.
